Abstract: Semiconductor nanocrystals (NCs) are promising materials for applications in photovoltaic (PV) structures that could benefit from size-controlled tunability of absorption spectra, the ease of realization of various tandem architectures, and perhaps, increased conversion efficiency in the ultraviolet through carrier multiplication. The first practical step toward utilization of the unique properties of NCs in PV technologies could be through their integration into traditional silicon-based solar cells. Here, we demonstrate an example of such hybrid PV structures that combine colloidal NCs with amorphous silicon. In these structures, NCs and silicon are electronically coupled, and the regime of this coupling can be tuned by altering the alignment of NC states with regard to silicon band edges. For example, using wide-gap CdSe NCs we demonstrate a photoresponse which is exclusively due to the NCs.

Abstract: Nanometer-scaled up-converting fluoride phosphor particles and processes of making them are disclosed. In the process, an aqueous solution consisting of soluble salts of rare-earth metal ions at a molar ratio of (yttrium, lanthanum or gadolinium): ytterbium:(erbium, holmium, terbium or thulium)=(70-90):(0-29):(0.001-15) is mixed a rare-earth metal chelator and a soluble fluoride salt to form precipitates, which are then annealed at an elevated temperature to produce nanometer-scaled up-converting fluoride phosphor particles. The particle size is between 35 nm and 200 nm, and can be controlled by the amount of the metal chelator added to the solution. The nanometer-sized particle is applicable to many biological assays.
